LAMP.

SPECIFICATION forming part of LettersiPatent No. 278,373, dated May 29, 1883.

Application filed March 5, 1883. (No model.) I

To all whom it may concern Be itlrnown that I, FnEEMAN'AUeUsTus TABER, a citizen of the United States, residing instance the bottom D is simply a shallow cup ,the air which supports combustion by an indirect or tortuous course in its passage to the wick-tubes, in order to lessen liability of the flame being extinguished by strong or irregular drafts of wind, and also to supply an abundant quantity of air to support combustion at theburner. y 7

My invention further consists in the peculiar construction of the lampbody, whereof the air is taken in at the top and caused to descend to the bottom thereof and return to. I the top before being admitted to the burner,

substantially as hereinafter described.

The drawings accompanying this specification represent, in Figure 1, a vertical section, and in Fig. 2 a horizontal section, of a lamp containing my improvements.

I In said drawings, A represents the oil-fount oi" alamp adapted to burn hydrocarbon oils.

or fluids, such oil-fount being inclosed within an outer case, B, of somewhat larger diameter and length,leaving a space, 0, between the two for passage ofair, as hereinafter explained. As small quantities of oilare liable to drip between the fount and its inclosing-case and collect in the bottom I) of the latter, I preferably connect such bottom to the sides in such manner. as to permit of its being readily removed to allow of cleaning. In the present tightly inclosing the bottom of the case B. The burner is shown at E as of ordinary construction, and screws into the filling-orifice of the oil-fouut in the usual manner.

In carrying out my invention I surround thelower part of the burner E and its air-supplying orifices a a, &c., with a hood, F, which connects the upper part of the burner with the lamp-body in such manner as to prevent direct access of air to the said air-inlets a to, thereby protecting such inlets,-and indirectly the flame of the burner, from liability of being extindrawings, into two parts by vertical partitions b b, which extend from the top nearly to the bottom of such space, between the oil-fount and case B, and I form in the bottom of the hood F an aperture, 0, which opens communication between the interior of such hood and one side, d, of the space O, as shown in Fig. 1 of the drawings, such side at being in reality Theflue d is covered at top to prevent entrance of air directly from the atmosphere to the burner through the aperture 0, while the opposite side or flue, e, of the space 0 is opeutothe atmosphere,but shut off from cominuhicationwith the burner by the hood F.

' The upper part of the passage or fine 6 iscovered by a foraminous or reticulated shield,f, through the interstices of which theair passes in entering the said flue. This foraminous shield f protects the interior of the flue e, and indirectly the burner, from sudden fluctuations or gusts of air outside of the lamp.

Under the above construction of a lamp air enters the mouth ofthe flue e by and through the reticulated shield f, descends such flue outside of the hood F, and passes across the bottoniof the oil-fount and ascends the flue dinto the interior of the hood F, and from thence to the burner by the air-inlets a a, &c. This construction of a lamp not only prevents ex tinguishment of the flame by undue drafts of air, but provides ample supply of oxygen to the burner.

I claim- 1. A lamp constructed as herein described, consisting of the oil-fount A, iuclosing-case B, burner E, hood F, preventing direct passage of air to the burner, and the fines d and e, the flue e communicating directly with the atmosphere and supplying the flue d, and the latter communicating with the interior of the hood,
